“Did you see my analogy?”
It has nothing to do with a community of women not driving.
“Today is a Minhag, tomorrow it becomes “Halacha” and reason not to give people Aliyot and other things and children banned from schools etc”
So, now you are a navi?
“Should we not protest?”
Is it abusive? Is a hanhaga not to drive abusive? Is anyone in this community not free to move elsewhere if they wish to drive? You are comparing apples and ptcha.
“This is a social construct unrelated to Halacha.”
Not every hanhaga is practiced to avoid violating a halacha. Some hanhagos are practiced to elevate onesself. You might disagree that this hanhaga does such a thing, but dont knock, or worse, attack as baseless and stupid those that take on such a hanhaga.
